Marie Gertrude Rand Ferree (October 29, 1886 – June 30, 1970) was an American research scientist who is known for her extensive body of work about color perception.
Her work included "mapping the retina for its perceptional abilities", "developing new instruments and lamps for ophthalmologists", and "detection and measurement of color blindness".
[1] Rand, with LeGrand H. Hardy and M. Catherine Rittler, developed the HRR pseudoisochromatic color test.
In 1959, Rand joined Christine Ladd-Franklin, Charlotte Moore Sitterly, Dorothy Nickerson, Louise L Sloan, and Mary E Warga as the five women part of the first Optica Fellow class.
[9] At Bryn Mawr, Rand's research focused on developing techniques for measuring the light sensitivity and color discrimination of different parts of the retina.
[7] In 1928, she left Bryn Mawr to join work for the Wilmer Ophthalmological Institute of Johns Hopkins School of Medicine in Baltimore, Maryland.
[9] Upon her husband's death in 1943, Rand moved to New York City as a research associate at Columbia University’s Knapp Foundation of the College of Physicians and Surgeons.
